Ingredients

2 5-pound bone-in prime rib roast
1 tablespoon of kosher salt
2 teaspoons black pepper
6 teaspoons fresh thyme leaves minced
7 garlic cloves minced
2 tablespoons olive oil
6 teaspoons fresh rosemary leaves minced.

Instructions

Heat your oven to 425°F (220°C).
Coat the prime rib in a mixture of kosher salt, black pepper, thyme leaves, garlic cloves, olive oil, and rosemary. Make sure all sides are evenly covered with this blend of seasonings.
Place the roast in the preheated oven for 15 minutes and then reduce the heat to 350°F (180°C). Roast the prime rib for an additional 1 hour and 30 minutes.
After roasting, take the prime rib out of the oven and let it rest for 10-15 minutes. Once cooled enough, slice and serve.

Notes

For a crispier crust, you can increase the oven temperature to 500°F (260°C) for the first 15 minutes of cooking.
You may need to adjust the roasting time depending on your oven and the size of your roast. Use a meat thermometer to check that it has reached an internal temperature of 145°F.
To ensure that the roast is perfectly cooked, use a thermometer to check that the internal temperature of the meat has reached 140°F (60°C) for medium-rare or 150°F (65°C) for medium.
If you want your prime rib served with gravy, you can make an easy pan sauce by adding 2 cups of beef stock to the roasting pan after removing the roast. Simmer on low heat until it reduces by half, then strain and serve.
